He has also produced, arranged and performed on hit singles for Harold Melvin & The Blue Notes, William "Poogie" Hart of The Delfonics, The Whispers, Regina Belle, Engelbert Humperdinck, The Dells, Isaac Hayes and Sister Sledge.

In 2007, Eli helped to unite three of Philly's most successful lead singers, William Hart of The Delfonics, Ted Mills from Blue Magic, and Russell Thompkins, Jr. of the Stylistics. The project was billed as the "Legendary Tenors of Soul" and featured the three vocalists alternating leads on mostly soul standards. Eli recruited Hall & Oates to join the soul trio for an original track on the CD, All The Way From Philadelphia.
